MECHANICAL MOVEMENT.

To all whom t may concern.'

Be it known that I, WILLIAM J. NEWTON, a citizen of theUnited States,residing at Bridgeport, county of "Fairfield, State of Connecticut, haveinvented an Improvement in Mechanical Movements, of which the followingis a Specification.

This invention has for its object to provide a mechanical movementespecially adapted for any of the various uses 1n which an exceedinglyquick movement of a part or parts is required, as in operating steam andhydraulic valves, making and breaking electric circuits, etc. Thisresult I accomplish by means of a striker which 1s caused through theaction of a spring controlled toggle joint, or equivalent means, tostrike a hammer blow upon a swinging member which I term the actuatingmember.

In the accompanying part of this specilication, v

Figure l is a side elevation illustrating an application of my novelmechanical move ment;

Fig. 3 a section on an enlarged scale on the line 3-3 in Fig. 2,lookingk in the direction of the arrows, and

Fig.l 4 is a sectional view illustrating a variant form of theinvention.

1() denotes a frame by which the parts are carried and which isconveniently made U-shape, although the special design of the frame isimmaterial so far as the principle of the invention is concerned. Theside pieces of the frame are shown as provided with attaching ianges 11by which it is secured in place. The actuating member is shown as doubleand consists of side pieces 1 2 which are pivoted on the outer sides ofthe side pieces of the frame, yand spaced apart pro# jections or crosspieces 13 connecting the lower ends of the side pieces. When anactuating member with a single side piece is used projections of coursetake the place of cross pieces. 14 denotes the striker, shown as madeU-shape, the side pieces of which are pivoted to the innery sides of theside pieces of the frame. In the present instance,- the actuating memberand the striker are shown as swinging from the same pivots, although itis immaterial whether or not they are pivoted concentrically. In theform illustrated in Figs. 1, 2 and, the toggle Specification of LettersPatent.

cross piece of the striker and is provided.

with a hole corresponding with hole 18. 2O

denotes a relatively strong compression i spring carried by the togglearm and bearing against the head of said arm and against the cross pieceof the striker or against the angle piece, if used. Washers 21 arepreferably interposed between the ends of thespring and the head of thetoggle arm and the angle piece, respectively.

The special mechanical connections by which the practicallyinstantaneous movements lof the actuating member, caused by the blows ofthe striker, are utilized in mechanical operations are immaterial so faras the present invention is concerned. I have shown two oscillatoryshafts, indicated by 22, which arejournaled in suitable bearings 23.Each shaft has extending therefrom a rigid arm 2e, said'arms beingloosely pivoted to ears 25 on the cross piecesof the actuating member.

The operation is as follows: It will be noted that the striker liesbetween the cross pieces of the actuating member which are spaced apartfar enough to give full effect to the blows of the striker. It is whollyimmaterial so far as the present invention is concerned whether theoperating member is operated mechanically or manually. In either casewhen the toggle joint is moved toward its dead center the spring will becompressed, the toggle arm sliding lfreely in the holes in the anglepiece and the cross piece of the striker. The lower end of the spring,or the lower washer if used, will ride up an angle oi the angle pieceuntil it reaches theapex of the angle piece. An instant later the washerwill start to ride down the other angle of the angle piece and rstarting position. It should be understood, however, thatthe device isperfectly operative if the angle piece is omitted. The toggle arm ofcourse carries the striker, so the result is, either with or without an.angle piece, that the full strength of the sprmg is exerted upon thestriker causing it to strike a 'violent blow upon the cross iece of theactuating member opposite to t e onev with which the striker waspreviously in contact. The operating member remains stationary until itreceives the blow and the movement 'of the actuating member is limitedby enj' agement of one of its cross pieces with the rame. In the presentinstance the instantaneous movements of the'actuatingI member will betransmitted by means of arms 24 to4 the shafts and will causepractically instantaneous oscillatory movement of the shafts.

The form illustrated in Fig. 4 diifers in that Ithe toggle arm, as anindependent element, is dispensed with and another type of spring isused which combines the functions of both'toggle'arm and spring. Theoperating member, actuating member,'and striker are the same as before.'In lieu yof the toggle arm and compression spring of ,y before.

the other form, I use a spring`comprising one or more coils 26 which liebetween the side pieces of the striker and in the plane of movement ofthe striker, and arms 27 which extend in opposite directions. One ofthese arms is pivoted to the operating member as at 28, the other armbeing pivoted near the free end of the striker, as at 29.

The operation is practically the same as The action of the combinedspring and toggle arm is to retain the toggle joint 4bowed and thestriker at one extreme or the' other of its movement. Manipulation ,o..the operating member will cause distoractin "tion o'fthe coils of thespring which will 'accumula-te power until the toggle jointhasreachedits neutral position or dead center. An instant later the springwill react and its full power will be exerted to throw the toggle jointto the other extreme 4of its movement, causing the striker to strike aviolent blow upon the opposite projection or cross piece of theactuating member and throw said member to the opposite extreme of itsmovement. v

Having thus described my invention, I claim: -Y

1. A mechanical movement comprising a swinging actuating member, astriker adapted to engage opposite sides of the actuating member, and aspring controlled toggle joint position until the joint has been swungpast its dead center and to then cause the striker to violently strikethe actuating member and throw it to the other extreme of its movement.

to retain the striker at its normal' frame, a swinging actuating memberpivoted thereto and having projections which engage the frame to limittheir movement, a swlnging striker, and means for causingthe striker tostrike a projection of the operating member and throw the latter to theopposite extreme of its movement.

3. A mechanical movement comprising an actuating member, a striker, anda spring controlled toggle joint which causes the striker to strike theactuating member when the joint is swung past its dead center.

4. A mechanical movement comprisin a swinging actuating member havingprojections, a swinging striker between the projections, and a springcontrolled toggle joint one member of which'has sliding e agementwiththe striker, whereby the atter `is caused to strike a projection of theactuat- ,ing member and throw the latter to the o posite extreme of itsmovement when tiie joint is thrown past its dead center.I 5.

A mechanical movement com rising a U-shaped frame, an actuating memer comprising side pieces pivoted outside the side pieces of the frameand spaced apart cross pieces, a U--shaped striker pivoted inside theside pieces of the frame and lying be- .tween the cross pieces of *theactuat" member, and a spring controlled togg e joint, one member ofwhich has sliding engagement with the striker. .Y

A mechanical movement com rising a U-sliaped frame, an actuating memer comprising side pieces pivoted outside the side pieces of-the frameand spaced apart cross pieces, a U-shaped striker pivoted inside theside pieces of the frame and lying between the cross pieces of theactuating member, an operating member, a toggle arm pivoted to theoperating member and having sliding connection with the striker, and acompression spring whereby the striker is caused to strike a cross pieceof the actuating member and throw {aid member to the opposite extreme ofits movement.
